Correct. I am familiar with setting up boot-args to get an NMI, but
that's not what I want here.
>how do you tell it which process?
How does Xcode tell which process to apply the pause button to? :) I
suppose one might be debugging more than one app at a time with Xcode,
but generally not.

Can one use AppleScript to tell Xcode to "pause" the app its debugging?
Then I could write a global doohickey that runs that script.

I'm debugging some old code that I don't know that does StillDown()
loops and I want to catch where those loops are, so I'm looking for a
way to break into the debugger while my mouse is down so I can find the
StillDown loop. I guess I could debug remotely, but I was hoping I
could somehow rig an F key to do it...
Thanks for your response!
